  • Patent number: 8152998
    Abstract: A liquid filtering apparatus is placed in a vessel having a bed of filtration material, the bed comprising at least two different sizes of filter media wherein the filtration material is stratified using upper and lower spaced apart inverted cones so that the unfiltered liquid first contacts coarse grained filtration material and then finer grained filtration material. The apparatus includes an intake for introducing unfiltered liquid that includes a washbox, an airlifting tube extending from the washbox and including an intake end and means for introducing a primary gas to the airlifting tube, the airlifting tube passing through a central pipe, which extends from just below the washbox to a position just above the intake end. The apparatus is devoid of screen cartridges. Methods of filtering and cleaning the filtration material are also disclosed.

  • Patent number: 7950451
    Abstract: Methods and apparatus are described that combine a measurement of the physical velocity of material within the annulus of a well between the drill pipe and the wall of the well with a measurement of the area of the flow as determined from a measurement of distance between the drill pipe and the wall of the hole to determine the actual material volumetric flow rate. Changes in volumetric flow rate at one or more points along the well can be used to determine the occurrence and location of well dysfunctions. This knowledge can then be used to make decisions about treating well dysfunctions which will lead to more efficient use of drilling rig time.

  • Patent number: 7741525
    Abstract: Processes and systems are provided for monitoring and blending a first stream and a second stream to produce a third stream of desired compositional characteristics. The processes and systems are found to be particularly useful for the blending of two or more hydrocarbon streams to economically produce a targeted hydrocarbon product stream meeting prescribed compositional specifications. Specifically, the processes and systems are found to be especially useful to blend a propane containing stream, having a vapor pressure lower than the vapor pressure of a targeted vapor pressure for a propane product, with an ethane containing stream. The blending processes and systems allow for production of an “on-spec” propane product stream while at the same time maximizing the value of the ethane stream. The processes and systems may incorporate continuous real-time analysis and flow control of the various streams to effectuate precise control the blending processes.

  • Patent number: 7706988
    Abstract: A method of predicting at least one physical change in crack geometry of a crack in a pipeline based on in-line inspection operating pressure is presented. In one method, a first test on a pipeline is performed at a first pressure, which obtains a first set of test data. A second test is performed on the pipeline at a second pressure, obtaining a second set of test data. The first and second sets of test data are compared for any difference. A run comparison software processing device may be employed. In other methods, finite element analysis of crack-like dimensions is performed to predict Crack Mouth Opening Displacement (CMOD) for a given set of crack dimensions for a surface-breaking crack and inline pipe inspection operating run pressure. Another method predicts probability of detection of a crack associated with a given CMOD as a function of pressure in successive inspections.
